Description

Die Erfindung betrifft eine kugelgelenkförmige Verbindung, wobei die Oberfläche eines kugelförmigen Schaftendes und der dazu entsprechenden kalottenförmigen Aufnahme wirkungsvoll gegenüber schädlichen Einflüssen von außen, wie Staub, Schmutz, chemischen Stoffen, Feuchtigkeit und Trockenheit, abgeschirmt wird. Insbesondere bezieht sich die Erfindung auf eine Kugelgelenkverbindung, wobei die Oberfläche der an einem Schaft oder Zapfen angeordneten Kugel und die Innengleitfläche der dazugehörigen Kalotte gegenüber den genannten Einflüssen von außen wirkungsvoll abgeschirmt wird.The invention relates to a ball joint connection, the Surface of a spherical shaft end and the corresponding one dome-shaped absorption effective against harmful influences from the outside, such as dust, dirt, chemical substances, moisture and Dryness, is shielded. In particular, the invention relates to a ball joint connection, the surface of which on a shaft or Spigot arranged ball and the inner sliding surface of the associated Dome effectively shielded from the above influences from the outside becomes.

Zum Stand der Technik gehören Kugelgelenkverbindungen mit einem ausreichenden zwei- oder dreidimensionalen Schwenkwinkelbereich, wobei bisher die Abschirmung des Gelenkbereiches gegenüber schädliche Einflüsse von außen durch an dem die Kugel tragenden Schaftbereich anliegende Einrichtungen, wie Schutzlippen, Manschetten und dergleichen, erfolgte. Bei der Benutzung solcher Kugelgelenkverbindungen wurde jedoch festgestellt, daß bei einer starken Auslenkung des Kugelzapfens sich die am Schaft anliegenden Abdichtungseinrichtungen wenigstens spaltbreit öffnen. Auf diese Weise können Staub, Schmutz, chemische Stoffe, Feuchtigkeit und Trockenheit in den Gleitbereich des Kugelgelenkes eindringen und dessen Gleitfähigkeit im Laufe der Zeit bleibend beeinträchtigen.The prior art includes ball joint connections with a sufficient two- or three-dimensional swivel angle range, so far the shielding of the joint area against harmful influences of outside by means of devices which bear against the shaft area carrying the ball, such as protective lips, cuffs and the like. In the However, using such ball and socket joints has been found to in the event of a strong deflection of the ball pin, those abutting the shaft Open sealing devices at least a little. In this way can cause dust, dirt, chemical substances, moisture and dryness in penetrate the sliding area of the ball joint and its sliding ability in Permanent impairment over time.

Die FR-A-2417672 offenbart eine Gelenkverbindung gemäß dem Oberbegriff des Anspruchs 1.FR-A-2417672 discloses an articulated connection according to the preamble of claim 1.

Der Erfindung liegt daher die Aufgabe zugrunde, eine langlebige kugelförmige Gelenkverbindung zu schaffen, mit der insbesondere die aufgezeigten, dem Stand der Technik anhaftenden Nachteile bezüglich der Dichtung beseitigt werden, bei gleichzeitiger einfacher Montierbarkeit.The invention is therefore based on the object of a long-lasting spherical To create articulated connection with which, in particular, the the disadvantages inherent in the prior art with regard to the seal are eliminated, while at the same time being easy to install.

Die Kugelpfanne kann aus einem kalottenförmigen Einsatz bestehen, von der mindestens eine Schutzlippe ausgeht, die an dem zapfennahen Oberflächenbereich der Gelenkkugel anliegt. Das Material des kalottenförmigen Einsatzes kann aus einem flexiblen Kunststoffmaterial bestehen, das in seiner sphärischen Gleitoberfläche Vertiefungen zur Aufnahme von Schmierstoffen aufweist oder in dem bereits Schmierstoffe integriert sind.The ball socket can consist of a dome-shaped insert, of which at least one Protective lip that goes out on the surface area of the joint ball near the pin is applied. The material of the dome-shaped insert can be made from one flexible plastic material, which in its spherical sliding surface Has depressions for receiving lubricants or in the lubricants are already integrated.

Eine besondere Ausführungsform der Erfindung besteht darin, daß anstelle einer Kugelpfanne ein Aufnahmelager verwendet wird, das aus einem harten festen Kunststoff bestehen kann. Ein Außenrand des Aufnahmelagers ist als ringförmiger Vorsprung ausgebildet. Der aus flexiblem Kunststoff gefertigte kalottenförmige Einsatz weist eine entsprechende ringförmige Aussparung auf, in die der ringförmige Vorsprung des Aufnahmelagers paßt. Die andere Seite des kalottenförmigen Einsatzes ist als ringförmige gegen den zapfennahen Bereich der Gelenkkugel gerichteten Schutzlippe ausgestattet. A special embodiment of the invention is that instead a ball socket a receiving bearing is used, which consists of a hard solid plastic can exist. An outer edge of the reception camp is as annular projection formed. The one made of flexible plastic dome-shaped insert has a corresponding annular recess, into which the annular projection of the receiving bearing fits. The other side of the dome-shaped insert is as a ring-shaped against the pin near Area of the joint ball facing protective lip.

Beim Auslenken des Kugelzapfens gleitet die Schutzlippe auf dem vorbestimmten Schwenkbereich der Kugeloberfläche, beispielsweise α und dichtet dort wirkungsvoll das Gelenk gegenüber schädlichen Einflüssen von außen, wie Staub, Schmutz, chemischen Stoffen, Feuchtigkeit, Trockenheit und dergleichen, ab. Diese Kugelgelenkverbindung ist einfach herzustellen, zum Beispiel nach der Spritzgußtechnik, und schnell zu montieren. Die erfindungsgemäße Kugelgelenkverbindung ist vielseitig einsetzbar. Die Kugelpfanne oder das Aufnahmelager mit dem kugelkalottenförmigen Einsatz kann in einem Schaft eingesteckt und befestigt sowie ggf.drehbar gelagert sein, während der Kugelzapfen um einen vorbestimmten Schwenkwinkelbereich auslenkbar in dem kugelkalottenförmigen Einsatz gelagert ist.When the ball pivot is deflected, the protective lip slides on the predetermined one Swivel range of the spherical surface, for example α and seals there the joint is effective against harmful external influences, such as dust, dirt, chemical substances, moisture, dryness and the like. This ball joint is easy to make Example after the injection molding technique, and quick to assemble. The invention Ball joint connection is versatile.
